Thermo-mechanical controlled processing (TMCP) is employed to obtain the required level of mechanical properties contemporary high-strength low-alloy (HSLA) steel plates utilized for gas and oil pipeline production. The strength, deformation behavior resistance formation propagation running fractures are mainly determined by its microstructure crystallographic texture. These formed as a result ...

Recycled aggregate concrete (RAC) is an environmentally friendly building material. This paper investigates the mechanical behavior of recycled aggregate concrete filled steel tube (RACFST) columns exposed to fire. Two groups of 12 columns were designed and tested, under axial compression, before and after fire, to evaluate the degradation of bearing capacity due to fire exposure. Six specimens...

The effect of hydrogen charging on the lattice dilation in an ASTM A710-HSLA steel specimen was studied using neutron diffraction. First, spatially-resolved strain measurements were made on a pre-cracked steel double cantilever beam specimen under a constant crack opening displacement (COD). Measurements were made at the crack tip region for in-plane and throughthickness lattice strains. Then, ...

• An HSLA steel was designed with the Fe 2 SiTi phase as its major strengthening phase. The Heusler phase, SiTi, can act grain refiner and precipitation strengthener. Precipitation behavior of compound is affected by Nb partitioning. Record high vol% nanosized precipitates lead to record hardness. remarkable combination strength, toughness, weldability that characterizes high-strength low-alloy...

Wire and arc additive manufacturing (WAAM) has been attracting industrial attention due to its high productivity flexibility. However, fatigue life data of WAAM HSLA steel is scarce. In this study, the mechanical properties thin-walled parts fabricated by were assessed via non-destructive destructive testing, providing a comprehensive analysis on material’s behaviour. The conditions have more p...
